Sanovi for Data Replication

Sanovi for Data Replications

Overview

A Disaster Recovery (DR) solution is the coming together of process and technology. DR solutions must be designed to meet two key recovery metrics: Recovery Point and Recovery Time. The choice of data replication is an important ingredient of the DR solution. It is primarily influenced by the Recovery Point required of the application. Sanovi’s DRM solution interoperates seamlessly with major replication technologies and offers monitoring and automation of replication processes.

Replication Technology and Management Complexity

An important consideration when choosing a replication technology is its ease of management: how easy it is to start, stop, and monitor replication. Block replicators, by nature, are more involved and require training and expertise for designing the right solution, setting it up, and monitoring its health and performance. Most block replication software supports a command line interface; additional software may be required to monitor and manage it with a graphic user interface (GUI).

Recovery of applications using block replication usually requires several steps to ensure that data is consistent before it is made available to the application. Block-based replication reports data lag between primary and remote systems in blocks or tracks. For this to be meaningful to the application it must be translated to the application recovery point, which is usually not an easy or obvious computation.

File replication must be faithful to file attributes and address security requirements. An important overhead for file replication is disk space management. The amount of available space on the primary and remote systems must be actively monitored; otherwise replication could fail if and when a disk runs out of space.
